Rockwell/Delta 46-111

Im always on craigslist and came across this lathe for $50 delivered! Of course I couldn’t pass that up. The main problem so far is the motor, it doesn’t work. It has power going to it, so its not the switch, but no life. I’m pretty inexperienced/wary of electricity so any ideas would be great. Anyone know where I can find out a manufacturing date? Serial FF-7026? Thanks!https://s3.amazonaws.com/vs-lumberjocks.com/nrp10dh.jpg!

If the motor isn’t seized up (shaft turns freely?), you could have a bad capacitor or bad centrifugal switch … that’s pretty common on older induction motors. If you have a local motor repair shop they should be able to fix you right up.

It spins fine, just seems like there is no juice going into the motor itsself. I have a little light up pen I keep handy to keep myself from getting electrocuted. I bI passed the switch to see if that was bad, but no luck. I’ll try to find a local shop. Any idea of the cost range for something like this?

I’ve got a midi shopfox I usually play on but wanted somthing that would be heavier and more balanced than a bench top. I figured for $50 I could either part it out on ebay and the larger shopfox for 500 or put a little money into the delta and use that.

Brad, I pulled the back off to see it there was anything obvious. When I would plug it in there was nothing happening so I was guessing that no power was getting through to the motor. If there had been a puff of that magic smoke, heat, or even current going through the coils I’d have felt a little less optimistic about the motor. How do I test the Klaxon? What and where would that be?

How did you test it? Just pushing the ‘reset’ button won’t work if it’s fried… there is a heating element inside of it that effects a thermal strip, which when heated sufficiently, bends and breaks the contacts. If the contacts are bad/dirty or the the heating element is bad, you can push that thing all day and it won’t do anything. I’ve run across several where they were wired wrong and the heating elements are fried. Here is the inside of one such example:

Note: there are usually three terminals on the back of the switch… only two are normally used. In the picture above, voltage comes in on the bottom left terminal, runs through the heating element to the bottom right terminal, and then the a bi-metal strip (not shown) spans to the upper terminal and out. You can see where the heating element in the one above is broken, just above where it comes in on the bottom left terminal.

Cheers,Brad

Brad, Here’s the switch from the back. The nut seems to be corroded on and when turned it starts backing the nut and bolt out together. When pressing the button there is no audible or felt click either. Should I just replace the switch for good measure? Where Would I Find One That fits? OEM looks to be discontinued.Thanks

Before you go about trying to replace it, you need to test it to see if it’s actually bad… which is why I asked if you checked it for continuity. Just eliminating one thing at a time that might be causing your problem.

Cheers,Brad

PS: Don’t try to open it up.. that will most likely result in breaking it… the one I showed was opened up just to show the internals and was already toast.
